<h1>To cast, casting</h1>
</center>
<hr>

If you want to change the 
<a href="../CONCEPT/data_types.html">datatype</a> of a variable 
you have to use a technic called <b>cast</b>. For example if want to 
change an <a href="../CONCEPT/data_types.html#int">int</a> to a 
<a href="../CONCEPT/data_types.html#float">float</a> 
you could use the following syntax:
<p>
<center>
<table border=1 width="80%" bgcolor="ivory">
<tr>
<td>
<pre>
        
    main()
    {
        int var1;
        float var2;

        var2 = (float)var1;
    }
</pre>
</td>
</tr>
</table>
</center>
<p>
As it happens this example would never be used in practice because C 
would perform the conversion automatically.

What this example does show is the cast operator<b> () </b>. This states, 
the result of the expression (in this case <b>var1</b>) is to be a  
data type of <a href="../CONCEPT/data_types.html#float">float</a>.
